Yes on selkirk. I dont think i have had duravent come apart with the band on right. But why bother with the band that can be put on wrong. Just put a few screws in each joint no way to do it wrong really.Really? even when twist locked and band installed properly? Something I'll have to look out for I guess. I usually have the opposite problem, getting them back apart after they've been in use for a while- of course there is usually no reason to take apart.
